Rotate with Raycast???
how can i get this to rotate when the raycast is no longer hitting the collider. This is for AI i want it to rotate when it hits the collider then move when it is no longer colliding been on with this for about 7 hours someone please help:(
function Update()
{
if(canMove == true)
{
if(distance <= rangeToAttack)
{
var forward : Vector3 = transform.TransformDirection(Vector3.forward);
var curSpeed : float = speed * Time.deltaTime;
robotController.SimpleMove(forward * curSpeed);
animation.CrossFade("walk");
transform.LookAt(player);
transform.eulerAngles.x = 0;
if(distance < 15)
{
animation.CrossFade("attack");
animation["attack"].speed = 0.3f;
}
}
}
var dir = transform.TransformDirection(Vector3.forward);
var hit : RaycastHit;
Debug.DrawRay(transform.position, dir * rayLength, Color.blue);
if (Physics.Raycast(transform.position, dir, hit, rayLength))
{
if(hit.collider.gameObject.tag == "Prop")
{
canMove = false;
transform.Rotate(0,rotateAmount,0 * Time.smoothDeltaTime);
}
else if(hit.collider = false)
{
canMove = true;
}
}
}
0 * Time.smoothDeltaTime isn't doing anyone any good. Otherwise, is the problem that it should continue to rotate for a little after getting clear?
yea it should rotate until the raycast is not hitting anything anymore
if (Physics.Raycast(transform.position, dir, hit, rayLength))
Raycast returns true if it hit something, false if it doesn't
else if(hit.collider = false)
this line makes no sense, hit.collider is the collider that the Raycast hit, you use it above correctly (hit.collider.gameObject.tag == "Prop") but here you are actually trying to assign false to it, I think this will always evaluate to false, and you'll never set canMove to true.
I think this is what you want:
if (Physics.Raycast(transform.position, dir, hit, rayLength)) { // rotate } else { // move and maybe attack } if (hit) rotate else move and maybe attack
There are some errors in the rotation part: as @OwenReynolds said, the 3rd parameter makes no sense - you should actually multiply the 2nd parameter by Time.deltaTime to make the AI rotate smoothly; another error: the instruction if (hit.collider = false) is wrong - "=" is the assignment operator, and collider isn't boolean anyway; you should use if (!hit.collider) or if (hit.collider==null) to do something when the collider doesn't exist.
That's the fixed code:
...
if (Physics.Raycast(transform.position, dir, hit, rayLength)){
if (hit.gameObject.tag == "Prop"){
canMove = false;
transform.Rotate(0,rotateAmount*Time.deltaTime,0);
}
else if (!hit.collider){
canMove = true;
}
}
NOTE: This is a syntax fix; I didn't check the logic.
